SQUARE ATTACHMENT FORSAW-BLADES.

SPECIFICATION forming part of Letters Patent No. 247,939, dated October 4, 1881.

Application filed April 20, 1881. (No model.)

To all whom it may concern:

Be it known that I, THOMAS U. MEKEEL, of Ponghkeepsie, Dutchess county, State of New York, have invented a new and Improved Oombined Saw and Square, of which the following is a specification.

The object of my invention is to provide for using ordinary hand-sawsas squares or bevels.

In the drawings, Figure l is a side elevation of the combined saw and square, and Fig. 2 is a cross-section through the saw-blade, showing the spring-catch.

Similar letters of reference indicate corresponding parts.

The blade A, provided with handlea, is that of an ordinary hand-saw. At-the heel of the bladeA bars or strips 1) b are attached bya pin, 0, passing through the blade, so that the bars are held one on each side of the saw.

The bars I) are formed with the edge or face toward the point of the saw straight and true, and they are of a length to extend nearly the full width of the blade A. As shown, they are pivoted at their mid-length, but they may be attached at the end next the back of the saw. The bars bconstitute the head otthc square or bevel, and can be turned on the pin 0, either one independently of the other, to bring their faces at any angle to the back edge of the saw.

Ordinarily they will beretained at rightangles, suitable fastening devices being provided to hold them. I have shown one bar I) recessed on the under side and titted with a'spring-artn, d, from which a pin, e, projects through the saw-blade into an aperture of the bar at the other side. The hole in the blade being properly placed, the pin 6 catches When the bars reach the right-angled position. Suitable means are provided for rt lieving the catch when it is desired to place the bars at an incline for use as a bevel, and a set-screw 'or other devices may be used in place of the fastening shown.

This construction furnishes acombined tool convenient for use, and combines two tools that are generally used together.

The attachment is inexpensive, and can be readily applied withoutinjury to the saw-blade.

Having thus described my invention, lclaim as new and desire to secure by Letters Patent A saw-blade provided with one or more pivoted bars, I), and the spring (1, having a bent end or pin, 0, which catches in an aperture of the bar, as shown and described.

THOMAS U. MEKEEL'.
